Question

我有一个Rails 4应用程序，我正在尝试管理员选择预约时间。

var Matrix = (function () {
    function Matrix(element) {
        this.ctm = element.getScreenCTM();
        this.element = element;
    }
    Matrix.prototype.apply = function () {
        this.element.setAttribute("transform", "matrix(" + this.ctm.a + "," + this.ctm.b + "," + this.ctm.c + "," + this.ctm.d + "," + this.ctm.e + "," + this.ctm.f + ")");
    };
    Matrix.prototype.flip = function (x, y) {
        if (x) {
            this.ctm = this.ctm.flipX();
        }
        if (y) {
            this.ctm = this.ctm.flipY();
        }
        this.apply();
    };
    Matrix.prototype.rotate = function (a, cx, cy) {
        if (a === void 0) { a = 0; }
        this.ctm = this.ctm.rotate(a);
        if (cx && cy) {
            this.ctm = this.ctm.rotateFromVector(cx, cy);
        }
        this.apply();
    };
    Matrix.prototype.translate = function (x, y) {
        if (x === void 0) { x = 0; }
        if (y === void 0) { y = 0; }
        this.ctm = this.ctm.translate(x, y);
        this.apply();
    };
    return Matrix;
})();

除了验证日期之外，我的模型对日期没有任何作用。在我的数据库（Sqlite）中，它将它们存储为时间对象。

我的控制器：

...
  <div class="field">
    <%= f.label :start_time %><br>
    <%= f.datetime_select :start_time %>
  </div>
  <div class="field">
    <%= f.label :end_time %><br>
    <%= f.datetime_select :end_time %>
  </div>
...

我已将默认时区更改为：

def create
  @user = User.find(params[:user_id]) 
  @appointment = @user.appointments.build(appointment_params)
  ...
end
...

def appointment_params
  params.require(:appointment).permit(:start_time, :end_time, :comments)
end

问题

我通过表单创建，然后像这样检查Rails控制台：

config.time_zone = "Pacific Time (US & Canada)"

即使我选择了（默认情况下是2015年），我也会得到这个。为什么Rails会像2000年那样存储年份？

修改 - 迁移

Loading development environment (Rails 4.2.2)
>> appointment = Appointment.all.last
Appointment Load (0.2ms)  SELECT  "appointments".* FROM "appointments"    ORDER BY "appointments"."id" DESC LIMIT 1
=> #<Appointment id: 8, user_id: 1, comments: "", start_time: "2000-01-01 12:50:00", end_time: "2000-01-01 12:50:00">
>> appointment.start_time.year
=> 2000

架构：

class ChangeTimeInAppointments < ActiveRecord::Migration
 def change
    remove_column :appointments, :time
    add_column :appointments, :start_time, :time
    add_column :appointments, :end_time, :time
  end
 end

Rails存储年份不正确
